The object of this invention is to facilitate the cutting, sanding, androlling of roofing-felt.

The invention consists in the machine for cutting, sanding, and rolling felt, constructed and operating as hereinafter described; in a mechanism whereby the knife will be operated with a quick downward movement and a slow upward movement; and in a peculiarly-constructed mandrel arranged so that the felt will be wound automatically and the felt. roll can be readily removed from the machine.

The invention also consists -in asnspended sand-hopper and a mechanism by which'the amount of sand discharged can be regulated,

and in the construction and arrangement of parts and details, as will be hereinafter more specifically set forth and claimed.

A is the frame of the machine, to the top of the rear end of which are attached two slotted standards, B, ,to receive the journals of the two rolls 0 C, or thebearings in which the said journals revolve. The'lower'r'oll, O, is grooved, as at D, to receive a number of belts, D, so

said belts D. The belts D also pass arounda roll, E, journaled in the middle part ofthe that the upper roll, 0, will not rest upon the.

To one of the journals of the lower roll, 0', is attached a crank-arm, H,

which is slotted to receive the crank-pin I, so that the said crank-pin can be adjusted to regulate the throw of the rod J, pivoted to the said crank-pin, as may be required. The other end of the connecting-rod J is piv= oted to the pawl K, which engages with the teeth of the ratchet-wheel L. The pawl K is pivoted to and supported by two bars, M, the lower ends of which have holes formed through them to receive and ride upon the hub of the ratchet-wheel. L,which wheel is placed loosely upon the shaft N, journaled in the lower part of the frame A, and is kept from being turned back by the friction of the pawl K,in its rearward movements, by a friction-brake formed of two bars, 0, placed above and below one end of the hub of the said ratchet-wheelL, connected at one end by a bolt, P, and connected at the other end and held in'place by a standard, Q, attached to the floor or the base of the frame A and having upon its upper end a screw -thread'and a'hand-nut, B, so that the friction applied by the said brake can be readily regulated as may be required. To the other end of the hub of'the ratchet-wheel L is attached, or upon it is formed, a crank-arm,

S, the crank-pin s of which engages with the crank-pin t of a crank-arm, T, keyed orotherwise secured to the shaft N. To the ends of the shaft N are attached crank-arms U, to which are pivoted the lower endsof the connecting-rods V. The upper ends of the con-. 'necting-rods V are pivoted to the endsof a cross-head, W, which slides up and down in slotted standards X, attached to the middle part of the frame A. Upon the ends of the cross-head W, or upon sliding cross-bars or bearings Y, attachedto the said ends, and

which slide upon the standards X, rest spiral. J;

'or other shaped springs Z, the upper ends of which rest against the caps 11, attached to the" upper ends of the slotted standards X, and

said springs are keptin place by guide-rods b, attached to the cross-head W and passing through guide-holes in the said caps a.

To the cross-head W is attached the upper knife, 0, the edge of which is beveled and is inclined from the center toward each end, as shown in Fig. 3.

dis the lower knife, which has a straight beveled edge and is attached to a cross-bar, e, secured to the frame A a little in front of the roll E, and in such a position that the straight side of the knife c,in its downward movement, will move along the straight side of the knife d, so that the felt will be cut with a shear cut.

Each of the cnnecting-rods V is made in two parts connected at their adjacent ends by a long right-and-left nut, f, or other suitable coupling, so that the said rods V can be readily shortened as the knives c d wear in use.

bringing the crank S into contact with the crank T and turning the shaft N until the crank U and knife 0 have'reached the upper points of their movements.

As the crank U passes the upper point of its movement,the weight of the connecting-rods V, the momentum of the fiy-wheelg, and the elasticity of the springs Z force the knife 0 downward,cutting the felt andturning theshaftNuntil the crank Uhas been carried past the lowest point of its movement and the knife 0 has been raised out of contact with the felt, the said shaft being held from being turned back by the ratchet-wheel h and pawl i. The shaft N and knife 0 remain stationary until the regular advance of the ratchet-wheel L brings the crank S again into contact with the crank T,and the knife 0 is again raised for another cut.

To the frame A, a little in advance of the knife d, is journaled a roll, j, around which pass a number of belts, k. The belts It also pass around a roll, Z, journaled to the forward end of the frame A. To the journal of the roll I, or to a journal of one of the rolls,C, is attached a pulley, m, to receive a driving-belt, n, to which motion may be given from any convenient power. To a journal of the roll I is attached a fast and a loose pulley, 0, around which passes a belt, The belt 9 also passes around the pulley G, attached to one of the rolls, 0.

The roll L is made larger than the roll 0, or the pulley o is made larger than the pulley G, so that the belts is will travel faster than the belts D and will roll up the felt after it is cut by the knives c 01 faster than it is fed to the machineand form a space between the rear end of the piece being rolled and the forward end of the following piece, to give the operator time to remove the roll of felt and replace the mandrel.

To the forward end of the frame A, or to the bearings for the roll I, are attached standards q, which are slotted to receive the journals of the mandrel r, and are inclined forward, so that the roll of felt can be readily removed and the mandrel replaced.

The body of the mandrel r is made in two parts or halves, the forward end of each part entering a socketed band, 8, attached to or formed upon each part at the inner end of its journal.

The adjacent faces of the parts of the mandrel r are beveled from the center toward each edge, so as to form, when the two parts are placed together, wedge-shaped openings, as

shown in Fig. 8, int-o which the end of the felt can be readily inserted when starting the roll. After the roll is started the winding will be continued by the movement of the roll I.

The mandrel r is placed in the slotted standards q, and when the end of the felt reaches the roll 1 it is inserted in the opening between the parts of the said mandrel and the said mandrel is turned to begin the winding. The winding is then continued by the action of the roll l.

As the felt passes to the roll l, it is sprinkled with sand or other desired material from the hopper t. The hopper t is formed with vertical ends and inclined sides, is suspended by jointed bars u from the ceiling of the room or other suitable support, and has a long narrow opening, 12, in its lower part, so that the sand will bedischarged in a thin sheet. The size of the discharge-opening and the quantity of sand discharged are regulated by a slide, 10, to which are hinged the lower ends of two or more bars, as. The upper ends of the bars a:

are pivoted to cranks formed upon the shaft 1 journaled in bearings in the upper part of one end of the hopper t and having a hand-wheel, 2, attached to a projecting end for convenience in turning it to adjust the silde w. The slide to is locked in place when adjusted by a handnut, 1, screwed upon the crank-shaft y.

To one sideof the hopper t is hinged the lower end of a connecting-bar, 2, the other end of which is hinged to the crank-pin 3, attached to the side of the pulley 4, journaled in brackets 5, attached to the ceiling or other suitable support. To the shaft 6 is attached a pulley, 7, to receive a belt, so that it can be driven from any convenient power to shake the hopper t, and thus insure a continuous discharge of sand. 4

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Amachine for cutting,'sanding, and rolling felt, consisting of the following elements combined for operation substantially as set forthviz., a feeding-belt, knives for severing the felt as it leaves said belt, delivery-belts moving at a quicker speed than the feedingbelt, a revoluble mandrel receiving the felt from the delivery-belt, and a sanding-hopper.
